ASC and stalling problems
Discussion
Hello all,
New owner here with a couple of problems:
1) Last night I was playing with a few of the controls in the car, the ignition was on but the engine was off. I then started the car and the ASC & TCS amber light came on with the warning message. A short drive around, stop and re-start and the problem went away. I have read that this could be caused by low battery voltage, but I wasn't playing with the electrics for more than a couple of minutes.
2) The other night, driving home, the engine stalled at a steady 60 mph. Stopped the car, into park and it re-started no problems - has been fine since.
Ah ha! (I thought) it's the throttle body, I rang Jaguar and it was replaced on my car as part of service action S514 on the 25th Nov 2004. So, the question is this, does it need replacing again or is it another problem altogether?
Thoughts and comments welcome guys, it's a '98 XJR with 92k on the clock.
(Doing some research I wonder if my two problems are linked:
This was on the following thread
"I was planning to start buying sensors, harnesses, module etc., but decided to unplug TPS plug on driver side of TB. It was late so I pulled it about 1/8 and decided to push it back on and deal with it later. When I turned ignition on next a.m., all problems disappeared. The degeneration of the tin to gold plug reported in the TSB on the appears to have been the cause. It makes sense when you think about how Trac control works....physical movement of car throws off degenerating prongs on plug. No problems on several drives...I will pick up gold to gold repair kit fm Jag ($14.50). Traction control is part of ABS anti-skid set-up. When I pushed plug on connection probably improved enough to cure problems....TPS sensor syncs braking with throttle to prevent skids and control traction. If you don't start here you could waste lots of money and wind up hating the car..... "

A bit more info on the ASC fault: If I drive home from work (about an hour or so) park up and then about 2 hours later turn the car on I get the fault. Take it for a short drive (less than 5 minutes) stop and re-start it goes away. If I then leave it overnight it'll be fine in the morning.
I have the asc light issue with mine.Go out for a drive and the light will start flashing and then power loss.I have looked at all different things to cure this but still no luck .....until the other day when i happened to be talking to a BMW specialist.He was timed served with Jag and he is almost certain,from what i explained to him,that it is the abs ecu/module.
